Technical Field
[0001] The utility model belongs to the field of astronomy teaching, and particularly relates to a sun, moon and constellation astronomy demonstration device. Background Art
[0002] "The sun rises and the moon sets, spring goes and autumn comes." The astronomical phenomena caused by the movement of the sun, moon and constellations often appear in the poems of the ancients, and they appear in the lives of modern humans all the time. The changes in the starry sky and the changes in solar terms brought about by them are closely related to human production and life. In astronomy teaching, astronomical demonstration devices can be used to demonstrate and explain the changes in the sun, moon and constellations and the starry sky. However, most of the existing astronomical demonstration devices cannot show the movement of the sun and the moon relative to the constellations, and cannot fully demonstrate the position relationship and operation law of the sun, moon and constellations. The teaching effect is not good, and no astronomical demonstration device can simultaneously present the altitude angle information of the sun and the moon to the earth, and predict the position of celestial bodies at future times. Therefore, it is necessary to innovate and develop a set of astronomical demonstration devices, use the demonstration devices to intuitively and real-timely present the relative position of the sun and moon constellations, predict the position of the sun and the moon, summarize the operation law of the sun and moon constellations, and explain their relationship with the principles of the human calendar.

[0005] (II) Technical solution
[0006] In order to solve the above problems, the utility model provides a sun-moon-constellation astronomical demonstration device, including a celestial sphere, a star disk, a sun, a moon, a bracket, a star disk drive, a sun drive, and a moon drive;
[0007] The celestial sphere is a transparent northern celestial sphere, the surface of which is marked with northern celestial constellations. The celestial sphere is fixed on a star disk, and the celestial sphere can be divided into thirteen angle regions according to the thirteen zodiac constellations, or can be divided into fifteen angle regions according to the fifteen constellations of the celestial equator;
[0008] The star disk surface is parallel to the celestial equatorial plane, and the star disk has an inner circle and an outer circle. The inner circle and the outer circle are respectively divided into thirteen and fifteen scale areas according to the projection of the angle areas corresponding to the thirteen zodiac constellations and the fifteen celestial equatorial constellations. Different scale areas represent different zodiac and celestial equatorial constellations and their corresponding dates. The star disk and the star disk drive are rotatably connected, and rotate under the action of the star disk drive, with the rotation axis pointing to the north celestial pole of the celestial sphere. The rotation speed of the star disk can be adjusted by adjusting the drive speed;
[0009] The sun and the sun drive are rotatably connected, and rotate around the rotation axis of the star disk and the celestial sphere under the action of the sun drive, and the rotation speed is adjustable, and the sun contains a sun pointer;

From the perspective of an earth observer, starting the demonstration device can truly present the relative position state and operation rules of the sun, moon, and constellations from a three-dimensional space perspective, clearly displaying the celestial movement, starry sky phenomena, and the relative position relationship of the sun, moon, and constellations from the perspective of the earth, providing assistance for astronomical teaching.
[0014] Furthermore, the demonstration device can present the movement status of the sun and the moon relative to the constellations and the relative movement status of the sun and the moon from the perspective of an earth observer, highlighting the movement relationship of the sun and the moon relative to the background starry sky, and more effectively explaining astronomical phenomena caused by the relative movement and position relationship changes of the sun, moon and constellations, such as "the sun rises earlier and the moon rises later than the previous day", "the position change of the moon relative to the starry sky is more obvious", and "the wandering of the sun and the moon on the zodiac constellations".
[0015] Furthermore, the inner and outer circles of the star disk have projection scales for the corresponding angle areas of the celestial ecliptic constellations and the celestial equatorial constellations respectively. When the sun and the moon move, the sun pointer and the moon pointer will be vertically projected into the corresponding constellation scale areas on the star disk. The demonstration device can display the pointer projections on the star disk in the form of two-dimensional projection, presenting the starry sky scene observed from the perspective of the earth, and intuitively and clearly presenting the constellation areas where the sun and the moon are located.

The demonstration device can not only assist astronomical observers to quickly locate the positions of the sun, moon and constellations in the actual starry sky and assist in astronomical observation, but also clearly display astronomical phenomena that are difficult to detect or observe in the actual starry sky, such as "the sun and the moon shine together" and "the relative movement of the sun and constellations" when the sun and the moon are both above the horizon, and vividly explain the reasons and mysteries behind the situation such as "although such phenomena occur frequently, humans rarely notice them".
[0017] Furthermore, the initial position states of the sun, moon and constellations in the demonstration device are set to be consistent with the actual states, and the rotation period is proportional to the actual period. Starting the demonstration device can present the constellation sky area where the sun and moon are located at any time in the past, present and future, and the relative positions of the sun, moon and constellations.

The output speeds of the three driving motors are adjusted to appropriate values that conform to the actual proportions according to the needs of the demonstration time. The demonstration device can present the diurnal and annual apparent motions of celestial bodies in a short period of time, which significantly improves the efficiency of the demonstration of astronomical phenomena of the sun, moon and constellation system.
[0019] Furthermore, by adjusting the adjustment frame in the demonstration device bracket, the angle between the demonstration device and the ground can be adjusted, and the angle is adjusted to be consistent with the latitude of the geographical location of the earth observer. When the demonstration device celestial sphere and star disk are started, they will rotate around the rotation axis pointing to the north celestial pole. At this time, the demonstration device can present the concepts of the north celestial pole, the celestial equator, and the north celestial constellation in three dimensions and teach them, and fully display the celestial body movement of the sun and moon constellation system in the equatorial coordinate system.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] like Figure 1 As shown, an astronomical demonstration device of sun, moon and constellations provided by an embodiment of the utility model includes a celestial sphere 1, a star disk 2, a sun 3, a moon 4, a bracket 5, a star disk drive 6, a sun drive 7 and a moon drive 8.
[0028] Among them, the celestial sphere 1 is a transparent northern celestial sphere, which is consistent with the appearance of the northern celestial sphere of the celestial globe. The surface of the celestial sphere 1 is marked with northern sky constellations. The celestial sphere 1 is fixed on the star disk 2. The celestial sphere 1 can be divided into thirteen angular areas according to the thirteen zodiac constellations, and can also be divided into fifteen angular areas according to the fifteen constellations of the celestial equator.
[0029] The star disk surface is parallel to the celestial equatorial plane, the star disk 2 has an inner circle and an outer circle, the inner circle and the outer circle are respectively divided into thirteen and fifteen scale areas according to the corresponding angle area projections of the thirteen ecliptic constellations and the fifteen celestial equatorial constellations, and different scale areas represent different ecliptic and celestial equatorial constellations and their corresponding dates, the star disk 2 and the star disk drive 6 are rotatably connected, and rotate under the action of the star disk drive 6, with the rotation axis pointing to the north celestial pole of the celestial sphere 1, and the rotation speed of the star disk 2 can be adjusted by adjusting the driving speed.
[0030] The sun 3 and the sun drive 7 are rotatably connected, and rotate around the rotation axis of the star disk 2 and the celestial sphere 1 under the action of the sun drive 7, and the rotation speed is adjustable. The sun 3 includes a sun pointer.
[0031] The moon 4 is rotatably connected to the moon drive 8 and rotates around the rotation axis of the star disk 2 and the celestial sphere 1 under the action of the moon drive 8. The rotation speed is adjustable. The moon 4 includes a moon pointer.
[0032] The celestial sphere 1, the astrolabe 2, the sun 3, the moon 4, the astrolabe drive 6, the sun drive 7, and the moon drive 8 are all fixed on the bracket 5, and the bracket 5 is provided with an adjustment frame.
[0033] The adjustment frame can adjust the angle between the demonstration device and the ground to be consistent with the geographical latitude of the earth observer.
[0034] The sun 3, moon 4, star disk 2, and celestial sphere 1 move around the same axis under the action of the sun drive 7, moon drive 8, and star disk drive 6, simulating the operation of the sun and moon constellations. The center of the celestial sphere and star disk is the imaginary earth, and the initial state of the sun and moon constellations is adjusted to be consistent with the real state, and the movement cycle is proportional to the real cycle. From the perspective of the earth observer, starting the demonstration device can truly present the relative position state and operation law of the sun 3, moon 4, and constellations from the perspective of three-dimensional space, clearly showing the celestial body movement, starry sky and relative position relationship of the sun and moon constellations from the perspective of the earth, providing help for astronomy teaching.
[0035] At the same time, the demonstration device can present the movement status of the sun and the moon relative to the constellations and the relative movement status of the sun and the moon from the perspective of earth observers, highlighting the movement relationship between the sun and the moon and the background starry sky, and more effectively explaining astronomical phenomena such as "the sun rises earlier and the moon rises later than the previous day", "the distance between the sun and the moon is getting farther and farther every day", "the position of the moon relative to the starry sky changes more obviously", "the wandering of the sun and the moon on the zodiac constellations" caused by the relative movement and position relationship changes of the sun, moon and constellations, while clarifying some common misunderstandings about astronomical phenomena in the sun-moon constellation system.
[0036] At the same time, the inner and outer circles of the star disk 2 have corresponding angle area projection scales of the celestial zodiac constellations and the celestial equatorial constellations, respectively. When the sun 3 and the moon 4 are moving, the sun pointer and the moon pointer will be vertically projected into the corresponding zodiac constellation and celestial equatorial constellation scale areas on the star disk 2. The demonstration device can display the pointer projections of the sun 3 and the moon 4 on the star disk in the form of two-dimensional projection, present the starry sky scene observed from the earth's angle, and intuitively and clearly present the constellation area where the sun 3 and the moon 4 are located. Combined with the date of the constellation area where the sun 3 and the moon 4 are located, the demonstration device can also intuitively explain the relationship between celestial movement and the human calendar from the perspective of phenomenon and principle.
[0037] At the same time, with the horizon projected on the star disk 2 by the actual ground plane of the geographical location of the earth observer as a reference, combined with the projections of the sun pointer and the moon pointer on the star disk 2, the demonstration device can demonstrate the altitude angle projection of the sun 3, the moon 4, and the constellations relative to the real horizon, and the state of the celestial bodies in the demonstration device is set to be consistent with the actual situation. The demonstration device can not only assist astronomical observers to quickly locate the positions of the sun 3, the moon 4 and the constellations in the actual starry sky and assist in astronomical observation, but also clearly present astronomical phenomena that are difficult to detect or observe in the actual starry sky, such as "the sun and the moon shine together" and "the relative movement of the sun and the constellations" when the sun and the moon are both above the horizon, and vividly explain the reasons and mysteries behind the situation such as "although such phenomena occur frequently, humans rarely notice them".
[0038] At the same time, the initial position states of the sun 3, the moon 4, and the constellations in the demonstration device are set to be consistent with the actual states, and the rotation period is proportional to the actual period. Starting the demonstration device can present the corresponding scale areas of the sun pointer and the moon pointer on the star disk 2 at any time in the past, present and future, the constellation area where the sun 3 and the moon 4 are located, and the relative positions of the sun and the moon constellations. Combined with the horizon projection of the observer's area, information such as the orientation of the sun 3 and the moon 4 relative to the horizon can also be obtained, thereby assisting astronomical science research and providing help for scientific exploration.
[0039] At the same time, the driving speeds of the sun 3, moon 4, and star disk 2 of the demonstration device are adjustable. According to the needs of the demonstration time, the output speeds of the three driving motors are adjusted to appropriate values that conform to the actual proportion. The demonstration device can present the diurnal and annual apparent motions of celestial bodies in a short time, significantly improving the efficiency of the demonstration of astronomical phenomena of the sun-moon-constellation system. The astronomical demonstration device allows astronomy enthusiasts to understand the operating laws of the sun-moon-constellation system and the astronomical phenomena produced without being affected by weather and visibility, effectively improving the practicality, interest, and convenience of the astronomical demonstration device, and can be widely used in experimental demonstrations and popular science exhibitions.
[0040] Moreover, by adjusting the adjustment frame in the demonstration device bracket, the angle between the demonstration device and the ground can be adjusted. The angle is adjusted to be consistent with the latitude of the geographical location of the earth observer. When the demonstration device is started, the celestial sphere and the star disk will rotate around the rotation axis pointing to the north celestial pole. At this time, the demonstration device can present the concepts of the north celestial pole, the celestial equator, and the north celestial constellation in three dimensions and teach them, and fully display the celestial body movement of the sun and moon constellation system in the equatorial coordinate system. By adjusting the angle to different values, the demonstration device can present the astronomical phenomena of the sun and moon constellations at different geographical latitudes, and has a wide range of applicability.
[0041] In this embodiment, the star disk drive 6, the sun drive 7, and the moon drive 8 use DC servo motors, and the output speed is accurate and stable, which can accurately achieve the operating speed that is strictly proportional to the actual celestial body of the actual sun and moon constellation system. After long-term operation, it can still present the same relative position and operating state as the actual sun and moon constellation system, and can accurately present and accurately predict the astronomical phenomena of the sun and moon constellations and the position of the sun and the moon relative to the earth. If a low-precision asynchronous motor is used for variable frequency speed regulation, it only needs to control the error within a certain range, and the above functions can also be presented by the demonstration device.
[0042] In this embodiment, the celestial sphere 1 is a transparent northern celestial sphere model, and the corresponding demonstration device can demonstrate the astronomical phenomenon of the sun-moon constellation system under the northern celestial constellation. If the celestial sphere 1 adopts the southern celestial sphere model, the rotation axis of the celestial sphere 1 and the star disk 2 points to the south celestial pole, and the star disk drive 6, the sun drive 7, and the moon drive 8 drive motors only need to be reversed, and the demonstration device can also demonstrate the astronomical phenomenon of the sun-moon constellation system under the southern celestial constellation.
[0043] In summary, the sun, moon and constellation astronomical demonstration device disclosed by the utility model can present the real-time position status of the sun, moon and constellations from a three-dimensional space perspective, comprehensively and clearly display the celestial body movement and the relative position relationship between the sun, moon and constellations, and efficiently teach their operation rules. It can also present the altitude angle projection of the sun and moon to the earth from a two-dimensional plane perspective, the constellation area and the corresponding date, which can not only display and predict the starry sky, but also intuitively explain the principles of the human calendar from an astronomical perspective. The demonstration device can effectively improve the practicality, fun and convenience of astronomical demonstration devices, and is widely used in experimental demonstrations and popular science exhibitions.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
